As Roger said, it was after midnight."

Vidac whirled and sat down again. He pressed a small b.u.t.ton on his desk and waited, silently considering the cadets, his eyes cool and level.

The door opened and Governor Hardy walked in, followed by several men.

Tom suddenly realized that it was the first time they had seen the governor in nearly six weeks.

"Have you found Professor Sykes?" he demanded.

Vidac shook his head, then turned to the other men. Tom, with a sudden sinking feeling in the pit of his stomach, recognized them as the colonists who had been with Ed Bush when Roger had his last argument with the professor.

"Did you hear Cadet Manning threaten Professor Sykes?" asked Vidac.

"Yes, sir," replied one of the colonists.

"What did he say?" asked Vidac. "Repeat it for Governor Hardy."

The colonist quoted Roger's threat almost word for word and Tom noted grimly that the witness made the most of the fact that he and Astro had followed Roger out of the office after the argument. The implication was clear that they were part of the threat.

Vidac then turned to Ed Bush. "Bush, did you see the cadets last night?"

"Yes, sir," said Bush.

"Where?" demanded Vidac.

"Leaving the swimming pool with the professor."

"With the pro--!" exclaimed Tom.

"Shut up, Corbett!" barked Vidac, and then turned to Astro. "Did you say you went swimming _alone?_"

"We did!" exclaimed the Venusian. "We left the professor at the office.

We did not see him again after that. He did not go swimming with us."

Vidac turned to Winters. "Did you see the cadets last night, Winters?"

"Yes, sir," replied the s.p.a.ceman. "I had the graveyard watch and I was in the galley having a cup of coffee. I saw the cadets enter the galley just as I was leaving."

"Were they alone?" asked Vidac.

"No, sir," said Winters. "Professor Sykes was with them."

"That's a lie!" shouted Roger. "We were alone!"

Vidac merely looked at Roger and then turned back to Winters. "Then what happened?"

"Well," said Winters, "they got into an argument, the cadets and Sykes.

It was about the movement of a captive planet, or something like that.

Anyway, there was a scuffle, and all of a sudden the big cadet"--he indicated Astro--"picked up the professor and carried him out of the galley. The other two followed."

"Didn't the professor put up a fight?" asked Vidac.

"Oh, yes, sir," said Winters. "But he didn't have a chance against the three cadets."

"Why didn't you do something about it?" Governor Hardy suddenly broke in.

"I tried, sir," replied Winters calmly. "I ran after them, but they all piled into a converted jet boat and blasted out of there."

"Then what did you do?" asked Vidac.

"That's when I came to get you, sir," said Winters. "And we started looking for them." Winters paused. "Ah--pardon me, sir, but can I go now? I've been up all night and I'm pretty tired."

Vidac nodded and Winters left the room.

"You mean you've been up all night looking for the cadets?" asked Hardy.

"Weren't they in their quarters?"

"No, sir," replied Vidac and turned to the cadets. "Well," he demanded, "what have you got to say for yourselves?"

The three cadets were silent.

"I must warn you," continued Vidac, "this is a serious matter and anything you say may be used against you. But on the other hand, if you speak freely and are willing to co-operate, I will do what I can to lessen your punishment."

Hardy suddenly stepped forward and slammed his fist on Vidac's desk.

"None of that! There'll be no favors to criminals!" He turned to the cadets angrily.

"What did you do with the professor?" he demanded.

The cadets kept silent.

"Where did you take him?" he shouted.

Neither Tom, Roger, or Astro batted an eyelash. They kept their eyes front and their lips tight.

"I warn you, you'll spend the rest of your lives on a prison rock if you don't answer!"

Tom finally turned and looked straight at the governor. "May I speak, sir?"

"Only if you tell me what you did with Professor Sykes," replied Hardy angrily.

"You have not asked us, sir," said Tom coolly, "to tell our side of the story. You are accusing us of a crime and have already a.s.sumed that we are guilty. We are not."

[Ill.u.s.tration: _Bush pulled a paralo-ray gun from his belt and said, "All right, march!"_]

"Do you deny it?" asked Hardy.

"We deny everything," said Tom flatly.

Hardy whirled around to face the colonists, Vidac, and Bush. "I want it clearly understood by everyone here that s.p.a.ce Cadets Tom Corbett, Roger Manning, and Astro, in the face of testimony given by eyewitnesses as to their argument with Professor Sykes, and their later abduction of the professor, do now conspire to withhold information which might help save the professor's life!" He turned to Vidac. "I want them arrested and held for investigation of their activities last night. Confine them to their quarters."
